I came across this thread from Mainly Norfolk.
I collected a tune for this song from Bill House of Beaminster in 1984
it's the Manchester Angel Tune. Bill insisted it was the Poacher song he had heard. A version of the Manchester Angel was collected in 1906 about 300 yards from Bill's front door, from old Sam Gregory the shepherd if my memory serves me. It found it's way into the Penguin book. I wouldn't mind some Dorset based words if any exist, Bill only had the tune. Just a thought.
